How it Works FAQs

For the last decade GFS has been on the leading edge of SVO technology and Methods

We’re pleased to showcase the latest generation of GFS components that were designed and manufactured to our specific criteria. Many of these components were designed exclusively by GFS from the ground up for SVO, and the specific requirements that provide a trouble free experience.

1 ) GFS Adjustable Purge ControllerAll GFS systems come with our 3V valve set and our adjustable quik purge capabilities. By controling our purge valve with GFS’s exclusive adjstable delay relay it allows you to fine tune your purge time for your specific vehicle.) The 3V assembly is controlled with a marine grade 3 position lighted switch. ON-OFF-Momentary. On for Vegetable oil, Off for diesel, and when you hit the momentary switch it triggers our exclusive GFS adjustable purge relay that flushes the engine with diesel and returns the vegetable oil to the appropriate tank. Once the purge is complete the light goes out, and you are on diesel.

2) 3V Triple Valve SetOur popular GV 10 valve has been redesigned. All aluminum construction with banjo fittings all the way around. Now mounted on a sturdy stainless steel bracket with multiple mounting holes for easy installation. All valves come with a weather tight wiring harness with 10 foot lead wires. Each wiring harness has an LED at the valve so you can confirm that you have power to the valve. The heart of the New GFS system is the 3V Assembly. Our new 3 Valve assembly offers ultimate control of your return flow. Looped when on vegetable oil, Return to Vegetable oil tank for purge and return to the diesel tank when running diesel.

6) Vented Fuel CapThe 2″ vented fuel cap allows you easy access to fill your tank. The 40 and 60 gallon trekker tanks also have a 6″ cap which allows you a large access port to the inside of your tank.

9) Filter Heater WrapOur heater wraps have been redesigned with a lower amperage draw and when used with our exclusive filter insulators, provide ample heat to melt the contents of your filter even on the coldest of days.

10) SVO Fuel FilterWe use the best filter in the industry. Period. Filtration is all about surface area, and our filters have the most, by a long shot (click here for more information). Our heated filters are insulated with a custom fit neoprene insulator, which allows us to use a heater that draws half the amperage of other heaters with the same performance.

12) 4B HoseOur exclusive 4B hose provides a coolant loop to your in tank heat exchanger while keeping your vegetable oil supply line hot from the tank to the engine. Our exclusive hose consists of 2 – 1/2″ coolant lines, 1 – 3/8″ vegetable oil return hose and our exclusive 1 – 3/8″ clear view vegetable oil supply line. This Clear View hose is the first clear vegetable oil fuel line that can withstand any type of fuel, pressure and heat and still retain it’s elasticity in cold weather. This hose is an indispensable window into the flow of your fuel system and is an unparalleled educational and diagnostic tool. It allows you to visually confirm what fuel you’re running on along with diagnosing air leaks and fuel flow problems. This hose also includes 3 – 12 gauge wires for your pump, sending unit and filter heaters allowing you to connect your system components in one easy step. This fuel bundle is insulated and protected by a rugged rubberized PVC sheath.

13) Wiring HarnessWiring your Golden Fuel System is easier and more straight forward than ever. With our exclusive GFS wire bundles connecting your gauges and switch in the cab of your vehicle to the wiring terminal is as simple as matching colors to numbers. Simply run the switch bundle and the gauge bundle through the firewall and connect your color coded wires to their appropriate terminals. No splicing, no guessing, a seperate wire for every terminal, color coded and straight forward.

14)Â 3 Position SwitchThe 3V assembly is controlled with a marine grade 3 position lighted switch. ON-OFF-Momentary. On for Vegetable oil, Off for diesel, and when you hit the momentary switch it triggers our exclusive GFS adjustable purge Controller that flushes the engine with diesel and returns the vegetable oil to the appropriate tank. Once the purge is complete the light goes out, and you are on diesel.

15) Terminal JunctionOur numbered terminal junction is the central wiring hub for your valves, pump, heater, sender, switch and gauges. As long as you can count and aren’t color blind, you will have no problem wiring your GFS system.

Customer Testimonial

It's been about 3 months since you converted our Jetta and we are very happy with it. We have only used one and one half tanks of diesel for 2000 miles+. Ironically, we don't drive much. With only a 16 mile round trip commute it's hard to use it all the time, but on a couple long road trips it has been great !
I had the oil changed at the local VW place and they have seen 4 or 5 conversions and they said yours was by far the most professional looking job.
Thanks again and happy new year!— Mark M., Oxford, IA
